I dont know the diff between boxer and berdan primed, all i can see inside 2 holes offset from the centre
Dear Spamhandler, thats interesting statement, btw what made you doubt my location, it might be fun talking about it.
Don't throw the berdan primed brass away. Modern primers will work the brass.
Several years ago I experimented with some berdan primed fired cases.
I put a case in a machinest vice on my drill press with the case head up. The vise has a notch that aliens the case perfectly vertical. I found that an 1/8" drill running slow (rpm wise) centered on the spent primer would just go through the primer bind and pull the primer out. It takes a little practice but I do it all the time now. Even some blazer aluminun cases can be refired once in pistol cases 45 acp that is.
